• The division of a quantity or phenomenon, such as a wave, with an infinitely variable range of values into one or more ranges with finite values, each called a quantized value. For example, the conversion of an analog input into a digital output. Since the number of subranges created can not be infinite, there will always be a loss, however minor, of information, called quantization error.
  • The division of a range of values into labeled subranges. For example, any number between 1 and 30 is a, between 31 and 60 is b, between 61 and 90 is c, and so on.
  • The description of an interval of values as a discrete number possible values. For example, anything occurring between 12 AM day one and 12 AM day two, being recorded as occurring on day one, regardless of the hour.
  • The process of applying quantum mechanics or quantum theory to something.
